Male Circumcision for the Prevention of HSV-2 and HPV Infections and Syphilis

Abstract: Background Male circumcision significantly reduced the incidence of human immunodeficiency virus (HIV) infection among men in three clinical trials. We assessed the efficacy of male circumcision for the prevention of herpes simplex virus type 2 (HSV-2) and human papillomavirus (HPV) infections and syphilis in HIV-negative adolescent boys and men. Methods We enrolled 5534 HIV-negative, uncircumcised male subjects between the ages of 15 and 49 years in two trials of male circumcision for the prevention of HIV and other sexually transmitted infections. Of these subjects, 3393 (61.3%) were HSV-2–seronegative at enrollment. Of the seronegative subjects, 1684 had been randomly assigned to undergo immediate circumcision (intervention group) and 1709 to undergo circumcision after 24 months (control group). At baseline and at 6, 12, and 24 months, we tested subjects for HSV-2 and HIV infection and syphilis, along with performing physical examinations and conducting interviews. In addition, we evaluated a subgroup ...

Complementarity and the use of indicator groups for reserve selection in Uganda

Abstract: A major obstacle to conserving tropical biodiversity is the lack of information as to where efforts should be concentrated. One potential solution is to focus on readily assessed indicator groups, whose distribution predicts the overall importance of the biodiversity of candidate areas1,2. Here we test this idea, using the most extensive data set on patterns of diversity assembled so far for any part of the tropics. As in studies of temperate regions2,3,4,5,6,7,8, we found little spatial congruence in the species richness of woody plants, large moths, butterflies, birds and small mammals across 50 Ugandan forests. Despite this lack of congruence, sets of priority forests selected using data on single taxa only often captured species richness in other groups with the same efficiency as using information on all taxa at once. This is because efficient conservation networks incorporate not only species-rich sites, but also those whose biotas best complement those of other areas9,10,11. In Uganda, different taxa exhibit similar biogeography, so priority forests for one taxon collectively represent the important forest types for other taxa as well. Our results highlight the need, when evaluating potential indicators for reserve selection, to consider cross-taxon congruence in complementarity as well as species richness.

Selection and fading of resistance mutations in women and infants receiving nevirapine to prevent HIV-1 vertical transmission (HIVNET 012).

Abstract: Objective To examine the emergence and fading of NVP resistance (NVP(R)) mutations in HIV-1-infected Ugandan women and infants who received single dose NVP to prevent HIV-1 vertical transmission. Design We examined NVP(R) in women and infants who received NVP in the HIVNET 012 clinical trial, including 41 out of 48 women with infected infants, 70 randomly-selected women with uninfected infants, and 33 out of 49 infected infants. Methods Plasma HIV-1 was analyzed using the Applied Biosystems ViroSeq HIV-1 Genotyping System. Results NVP(R) mutations were detected in 21 out of 111 (19%) women tested 6-8 weeks after delivery. The rate of NVP(R) was similar among women whose infants were or were not HIV-1 infected. K103N was the most common mutation detected. NVP(R) mutations faded from detection within 12-24 months in all 11 evaluable women. High baseline viral load and low baseline CD4 cell count were associated with development of NVP(R). NVP(R) mutations were detected in 11 out of 24 (46%) evaluable infants who were infected by 6-8 weeks of age. The most common NVP(R) mutation detected in infants was Y181C. Those mutations faded from detection by 12 months of age in all seven evaluable infants. Of nine evaluable infants with late HIV-1 infection, only one had evidence of NVP(R). Conclusions NVP(R) was detected more frequently in infants than women following NVP prophylaxis, and different patterns of NVP(R) mutations were detected in women versus infants. NVP(R) was detected infrequently in infants with late HIV-1 infection. NVP-resistant HIV-1 faded from detection in women and infants over time.
